What is the name of the metal ring inside the tire?
2 Answers
The steel ring inside the tire is called the wheel hub. The wheel hub, also known as the rim, steel ring, wheel, or tire ring, is a cylindrical metal component that supports the tire from the inside and is mounted on the axle. Relevant introductions are as follows: 1. Wheel hubs on the market can be divided into steel wheel hubs and alloy wheel hubs based on material, each with its own advantages and disadvantages. 2. The main advantage of steel wheel hubs is their simple manufacturing process and relatively low cost, along with strong resistance to metal fatigue, making them both affordable and durable. However, the disadvantages of steel wheel hubs are relatively prominent: they are unattractive in appearance, heavy, have high inertial resistance, poor heat dissipation, and are prone to rust.
I often deal with car components, and that metal ring inside the tire is called the rim, which serves as the core support structure of the tire, keeping it firmly attached to the wheel. Rims are typically made of steel or aluminum alloy, making them quite sturdy and durable. During everyday driving, the rim bears the vehicle's weight and road impacts. If it becomes deformed or rusty, it may cause tire leaks or wobbling, significantly affecting handling. I recommend regularly checking the rim for dents or corrosion, especially after driving on bumpy roads. Some cars also use rims made of different materials, such as aluminum alloy, which is lighter and can improve fuel efficiency, though at a higher cost. When changing tires, technicians pay special attention to the rim to ensure a good seal and prevent issues at high speeds. Simply put, although the rim may seem insignificant, it plays a crucial role in safety and comfort—don’t overlook minor issues with it.
